TFT 800 X 600 - 7" [SOLVED]

[Rafael Hackmam]

Hello Mr Garcia

We (I and my friend) have started a new Project in my reef (800 L) with FERDUINO Project to controller all the tank.
But a need you help with TFT!!!!
Your project user TFT 3.2" but I bought TFT 7" and we have a problem to installation, because the TFT screen no shows the information of calibration only white screen.

We are using your electrical diagram for installation at the components step by step.
We can to send information to explain with more detail or photos to stage that we stopped.

Hi!

Welcome Rafael!

I don't know any TFT with resolution of 800 x 600.

Best regards.

[Rafael Hackmam]

Sorry resolution is 800x480.

[Christopher Kindig]

check Dale's build thread I believe he has a 7" tft display.

[Fernando Garcia]

Hi!

In fact the code for 7" was done by Willie.

The topic is here: viewtopic.php?f=18&t=35

Best regards.

[Christopher Kindig]

yes Willie sorry for the mix up I was trying to remember who did it, Thanks Fernando.

[Rafael Hackmam]

Hi!!! Fernando

I verified the topic by Willie which you suggested but yet I'm with the same problem (white screen).

In bellow any pictures of the Arduino Installation

White Screen

Arduino Installation

TFT installation based in your schematic electric Led_A Installation with 1 resistor

53 pin to 5 pin

53 pin to 10 pin

TFT schematic 7" - Do you suggest I use this?

Best Regards

[Christopher Kindig]

I am not sure I fixed my white screen issue by accident, and can not remember what I did to resolve it. I do know I had had to go by the schematics for the screen, I have the same shield as well so at this point I would say use the schematics and verify voltage and grounds. Have you down loaded hennings lib for tft? it can be found here

[Rafael Hackmam]

Thanks Christofer

What is the libraries I need to download?

[Christopher Kindig]

Utft and utouch

[Fernando Garcia]

Hi!

I can see many things wrong here.

1 - In Willie's topic have a link to his Github where you can download the code with all libraries. https://github.com/willie111/Feduino_wi ... 7_Joy_Reef

2- To start connect the TFT directly on TFT shield and Arduino without anything else.

Best regards.

[Christopher Kindig]

Hi Fernando. I remember when went through this same thing the way I fixed was as you suggested with those two library from Karl henning site, or have they changed somthing?
And yes I agree just the screen on the shield was one step we had.

[Rafael Hackmam]

Hello Guys

I downloaded the all file from Willie.

But I didn't have success, because the code have "error"

Started with calibration but error

I try to change the code CTE70 and pins 7,6,5,4,3 but error

And other try I put de complete code, but error

[Fernando Garcia]

1 - I told here 1 TON of times to use IDE 1.0.6.

2 - The pins for touch are 6,5,4,3,2.

The problem is other, the users have problems by do not pay attention in my instructions.
In 1 download have all files needed.

[Christopher Kindig]

Okay I see. What did they change on the new ideas or do we just know it doesn't work?

[Rafael Hackmam]

Hello Guys

Thanks your help.

UTouch Calibrations OK but the complete code NOK

What are the error now?

[Fernando Garcia]

Use UTFT library downloaded with Willie's code.

[Rafael Hackmam]

Hi Fernando

Today I'm very happy because I had my first success. But only one!!!!

I could calibrate the TFT and execute the examples "UTFT_Demo_800x480".

After then I tried UTOUCH_Button Test, but the TFT code was ITDB32S,

So I changed it to CTE70 and request verification

The Arduino changed CTE70 for ITDB32S and some errors

Could you help me?

PS: All the test I use Willie's code

[Fernando Garcia]

Hi!

Are 2 tabs with code equal opened. Close one.

Best regards.

[Bruce Hardin]

I want to know the specifications of the TFT you are using based on its current and voltage characteristics.
Also which interface it uses with the board?
Can you please tell me which other displays are compatible with this board?
